ADAPTIVE LED HEADLIGHTS

Outline

Functions

Glare-free high beam

•  Depending on the presence of vehicles ahead, driving around curves, traveling through towns and cities, or vehicle speed, the glare-free high beam helps prevent the drivers of other vehicles from being dazzled while the maintaining headlight high beam light distribution.

Wide-range low beam

•  The wide-range low beam enhances the visibility at intersections during the night by illuminating the side-illuminating LEDs of the front combination light while traveling at low speeds.

Highway mode

•  The highway mode raises the optical axis of the headlight low beams to improve long distance visibility while traveling at high speeds.

System conditions display function

•  The forward sensing camera (FSC) displays the system status using the adaptive LED headlights indicator light (green) and adaptive LED headlights warning light (amber) in the instrument cluster, and the warning display on the center display.

Personalization feature

•  The adaptive LED headlights can be set to ON (operational)/OFF (non-operational)(initial setting is ON (operational).) For details on the personalization features, refer to the [i-ACTIVSENSE PERSONALIZATION]. (See i-ACTIVSENSE PERSONALIZATION.)

Operation

Glare-free high beam

•  The adaptive LED headlights control module determines the vehicle driving status and surrounding conditions based on the signals from the related modules, and based on the determined result, the Glare-free High Beam controls the on/off/increase and decrease of brightness for the LEDs installed on the headlight high beams.

•  When the glare-free high beam operates with all the following conditions met.

―  Adaptive LED headlights personalization is ON (operational)

―  Headlight auto leveling system initial setting is complete

―  Selector lever/shift lever is in position other than R position

―  Light switch in AUTO position and dimmer switch in HI position

―  Vehicle speed is 40 km/h or more

―  Driving in city/town signal is not received from FSC

No vehicle ahead and not driving on a curve (normal)

•  The adaptive LED headlights control module turns on the LEDs installed to the headlight high beams when there are no vehicles ahead and when the vehicle is not cornering.

When there is a vehicle ahead (divided light distribution)

•  The adaptive LED headlights control module turns off the LEDs located on the headlight high beams that are emitting light on a vehicle ahead, based on the vehicle detection signal from the forward sensing camera.

Driving on a curve (variable light distribution)

•  The adaptive LED headlights control module determines the lanes curve direction and curve length based on the lane condition signal or vehicle signal from related modules from the forward sensing camera (FSC), it then raises the LED on the inner side of the curve and lowers the LED on the outer side of the curve.

High beam inhibition

•  When the adaptive LED headlights control module receives a driving in city/town signal from the forward sensing camera (FSC), it turns off the high beams and inhibits unnecessary brightness.

Flicker inhibition

•  The adaptive LED headlights control module delays the change in light distribution and inhibits flickering under the following conditions.

―  Losing sight of vehicle ahead due to sloping road conditions

―  Appearance/disappearance of vehicles ahead is due to effect of dividers lining the median strip

―  Light distribution is performed

Wide-range low beam

•  The adaptive LED headlights control module increases the brightness of the LEDs for side illumination in the front combination light when all the following conditions are met.

―  Adaptive LED headlights personalization feature is ON (operational)

―  Headlight auto leveling system initial setting is completed

―  Selector lever/shift lever is in position other than R position

―  Light switch in AUTO position and dimmer switch in HI position

―  Vehicle speed is 2 km/h or more, or less than 40 km/h

Highway mode

•  The adaptive LED headlights control module operates the highway mode when all of the following conditions are met.

―  Adaptive LED headlights personalization feature is ON (operational)

―  Headlight auto leveling system initial setting is completed

―  Selector lever/shift lever is in position other than R position

―  Light switch in AUTO position and dimmer switch in HI position

―  Vehicle speed is 95 km/h {59 mph} or more

―  Driving in city/town signal is not received from FSC

•  The adaptive LED headlights control module raises the headlight low optical axis depending on the vehicle speed. For the headlight low optical axis adjustment, refer to the [HEADLIGHT LEVELING ACTUATOR]. (See HEADLIGHT LEVELING ACTUATOR.)
